The Croatian midfielder could be on his way out of Real Madrid if the club manage to sign Paul Pogba.
Reports link Real Madrid with an £80m move for Juventus star Paul Pogba, which could see an exit for a number of midfielders.
The future of Luka Modric would be most under speculation as the Croat is linked with a move back to the Premier League.
According to reports, Chelsea are the most likely club to sign the former Spurs man, as Jose Mourinho looks to be reunited with his former midfielder.
The Blues appear eager to bring in a midfield option as they have also been linked with a £10m move for Alex Song to act as back-up for Serbian star Nemanja Matic.
Both Manchester City and United have also been linked with swoops for Modric but it is understood that neither side are primary destinations for the 29 year-old.
